Just wondering if others running the Ferrodo pads get sqealing from them? The only time mine don't do it now are when they are cold but after a couple of light stops they start squealing! In traffic they just then seem to get louder. They work amazingly well but I'm just finding it a little embarrassing. They have got worse over the last 5,000 miles and have a total of around 10,000 miles on them now. I fitted them with a pair of new skoda 312mm disks when I did the upgrade. Any advice welcome.

Did you bed them in or lathe the discs first?

I take it you had a little Copper Slip on the back of the pads when you fitted them,

have you had the pads out & checked and some more applied since?

Would you not be better now fitting a set of suitable pads for the Cold Months?

Thanks for the replies guys. The brakes were bedded in properly and weren't too loud when new. They've got worse lately.

Yes, I used copper slip, I may give some more a go tomorrow but it just sounds like the contact of the actual pad to disk thats causing the squealing. I don't have any issue with performance of the pads in cold weather; they were great in zero conditions in Germany and Switzerland last year.

Fitted for 10,000 miles, Squeeling for 5000 miles and you have not looked at them, or given them a little grease on the back?

If you are using them for the reason you pay the money for them, Fast Road use, then they may just have lasted their life but have plenty of meat. (cooked often enough now)

They probably do stop OK with uprated brakes when cold,

but no better than standard pads would when cold.

(they will do exactly as they are designed to when hot i am sure)

Your problem comes if ever a child walks out in front of you as you set off, and even tho the Brakes work fine, you still are not stopped quick enough

it then goes on the Inspectors ramp & there are DS2500's fitted for road use. (track use only)

Yes i know they pass the MOT brake test, but they do not pass the Insurance Assessor or Police Vehicle Inspector test.

I have DS2500 pads in my Mk 1 octy VRS. They do start to squeal when performing normal day to day driving. So a good blast with some heavy breaking shuts them up.

Not sure which post you were reading but I never said I hadn't looked at them! Vie inspected them a number of times since they started squealing and now I'm home after the trip I've posted up here for opinion. They stop in a shorter distance from cold than the standard setup does so I have no worries about your scenario.

That's good advice! Im wondering if they were glazed as I've given them some hard use last night and they have certainly been quieter today! Thanks for the advice. :-)

As the friction material on these is different to everyday pads, I'd certainly take a read through this:

I've followed it for quite a few years and it's always done me well

They will need some fast road use every now and again through their life too, as already mentioned. But then again, that's why you've bought them

Thanks Wardy, that's a great link, very similar to the one i use from the GTR forum for bedding in but I really dislike the idea of holding the pedal down so that the pads are in contact with the disk surface after heating them up so much. Thinking back around 5,000 miles back, I had the pads smoking pretty badly on the Grossglockner pass in Austria, I let them cool off before continuing but it's since then quite possibly that they have been squealing badly.

Yep, that Austrian incident may have upset them! It's probably the cooling down period afterwards that's caused an unevenness in the pad material as it's cooled down. Or you've got small bits of pad fused to the disc

Difficult to know without stripping the brakes down whether it's the pad or disc to blame. I would re-run the guide and see if that helps.

Thanks again. Ive decided to get the wheels off over this coming weekend and give them a proper going over. I'll ensure they are all ok and then take them out and redo the bedding in advice. Hopefully this will resolve it as in every other way, they are exceptional pads. :yes:

Good stuff. I've never had the issue you're experiencing with them and found them to be fine from cold. But then I never got them fully smoking!

So yeah, give them a good bedding in again and you should be good

I'll probably look at ECB red or yellow next time, although that's purely for the r90.

The ds2500 stop well and if you're happy around the r90 issue then they're a good pad. Some firm slows from 70 to 10 and when cooled some new copper grease on the back. If the pads were smoking there's a good chance the grease cooked and now you have a squeal.

I was wondering when R90 was going to pop up

Aye, but it's down to personal preference if you're happy running the pads or not.

They stop very well when hot and I don't feel that they're any worse than the OEM pads when cold

Wear sensors are an annoyance, but easily bodged or coded out.

As Lee is already running them, it's a null point - if it were a purchasing thread however....

The wear sensor is an annoyance but is on the list for Shark to code out when it next visits them. I had a bad experience with EBC brake products many years ago so wouldnt touch them again tbh. The only better pads Ive used compared to these DS2500's were Mintex Xtreme pads and they were absolutely excellent. I ran them on my little Fiesta TDCi - 300mm ST brakes, decent fluid, steel braided lines and the Mintex pads and with decent rubber it would stop on a penny! Sadly they stopped producing them! Possibly the most effective overall brake set up Ive had actually... Anyway, I digress, that'll be the Merlot making me loose focus.... ;-)

Sorted! Now quiet as a church mouse again! Thanks again for the helpful advice in getting there!

Glad to hear you got there with them

I know my DS2500's didn't make a noise but I have heard of others getting noise and some not.... It also seems to be a bit of a luck of the draw too :(

In my experience, from extensive use in my Fabia and Octavia vRS, the DS2500s are not a 'quite' pad in use, in the way most OEM pads are 'quite', but this is purely down to the nature of the pads and their good stopping power.

I did find them, the DS2500s, quite a 'dusty' pad though and this is always, IMHO, a recipe for build up of dust and the pads glazing over; particularly if they are only used lightly as tends to happen with a lot of gentle and/or urban driving (and as I suspect FocusZetec does on a daily basis).

The cure for this is some speed and firm application of the brakes; usually achieved on my homeward commute where I have a downhill, sweeping, tightening, slip road exit off the A1(M).

I tried DS2500s in my Yeti but had an issue with them being loose in the calliper and getting, from time to time, a metallic 'click' when applying them. Demon Tweeks were very good and got me a full credit, which I then used, having read quite a number of reports, tests, reviews and forum chat that suggested they had improved markedly from where they were a few years back, to buy a set of EBC RedStuff.

These are excellent, day to day, do not produce much dust but perhaps do not have quite the ultimate stopping power of DS2500s. I'm more than happy with them.

The link is not far off the 'bedding in' instructions that come with DS25000s, IIRC.

To the average motorist it seems extreme, but to us enthusiasts should be second nature.

Glad to hear you are happy with the EBC, I think there is a lot of personal feelings when it comes to brakes, I have used EBC many of times, a while back and recent and never been happy with them. But it also depends on driving style, As mentioned the DS2500's I have ran always have been quiet, Maybe I was just lucky!

But for me, it is either Ferodo or Tarox every time now

Awesome Mike

Couldn't agree more - and I remember comments about the procedure being overkill from some, when it's been discussed previously.

But at the end of the day, for a fast road or performance pad, those are necessary steps to follow in order to get the best service from them.

Sorry double post

DS2500's are prone to squeaking.

Wardy, interesting you've linked to Seloc as that's my Lotus forum, only about 15,000 posts for me!

It can depend on the discs as I have Pagid RS14's on my Elise, the fronts came off a guys Exige as they made such a commotion he couldn't bear them - they are totally silent on my disks.
